Introduction
Using the Yelp API, I pulled data on 50 restaurants in the State College area. This is an exploratory analysis of the restaurant ratings.
Overall Ratings:
## Min. 1st Qu. Median Mean 3rd Qu. Max.
## 2.50 3.50 4.00 3.78 4.00 5.00
At first glance, it seems people generally enjoy the restaurants, with a median rating of 4 stars, and none below 2.5.
However, we have not taken into account the number of reviews that these restaurants received.
Number of Reviews
## Min. 1st Qu. Median Mean 3rd Qu. Max.
## 1.00 24.25 49.00 76.66 115.00 277.00| name | review_count |
|---|---|
| Cafe Alina | 2 |
| Central Reservation | 2 |
| Hello Bistro | 5 |
| Yallah Taco | 1 |
The median number of reviews is 47.5. There is one restaurant with only one review, Yallah Taco (the new location on W. College Ave). There are 3 other restaurants with 5 reviews or fewer: Cafe Alina, Central Reseration, and Hello Bistro. I note that all 4 restaurants are relatively new, having opened in the last year to year and a half.
| name | review_count |
|---|---|
| Faccia Luna Pizzeria | 277 |
| Little Szechuan | 229 |
| Big Bowl Noodle House | 220 |
Faccia Luna, Little Szechuan, and Big Bowl Noodles are the most frequently reviewd restaurants.
Ratings and Number of Reviews
The scatterplot indicates no relationship between the number of reviews and the overall restaurant rating. There is a weak correlation between the two variables, r=rcor(restaurants$review_count, restaurants$rating).
Top Restaurants
The 6 most highly rated restaurants are:| name | rating | review_count |
|---|---|---|
| Cafe Alina | 5.0 | 2 |
| Crust & Crumb Cafe | 5.0 | 6 |
| Penn Pide | 4.5 | 50 |
| Sowers Harvest Café | 4.5 | 134 |
| Roots Natural Kitchen | 4.5 | 23 |
| Juana’s | 4.5 | 14 |
The top-rated restaurant in State College is Cafe Alina with a bangin’ 5 star rating. However, since Cafe Alina only has 2 reviews, the rating we see may not be representative of the true customer experience. The two customers who reviewed may have had a particularly enjoyable experience at the restaurant and felt compelled to share their amazing experience.
Bottom Restaurants
The 6 most poorly rated restaurants are:| name | rating | review_count |
|---|---|---|
| Weirdough | 2.5 | 6 |
| Uncle Chen’s | 2.5 | 90 |
| BRGR | 3.0 | 48 |
| Hello Bistro | 3.0 | 5 |
| Are U Hungry | 3.0 | 40 |
| Mad Mex - Happy Valley | 3.0 | 204 |
We see that Weirdough, which opened just this past September, is off to a rough start. Uncle Chen’s Mongolian is tied for last place in the ratings.
